Installation Notes

  1. Relieve pressure and flush the pump per manual; lock out air.
  2. Disassemble the fluid section and remove the worn piston valve.
  3. Inspect seat/bore; clean and lightly lubricate per coating compatibility.
  4. Install the new assembly with correct orientation; torque to spec.
  5. Reassemble, prime with compatible solvent/coating, and test at low pressure.

Pro tip: Replace mating packings and check balls during the same service to maximize seal life.

When to Rebuild / Replace

  • Loss of prime or pressure creep at steady RPM.
  • Excessive pulsation or chatter from the fluid section.
  • Backflow seen at outlet when parked at pressure.
  • Visual wear, pitting, or scoring on valve components.
